NAME ^

Jifty::Plugin::Comment::Mixin::Model::Commented - add comments to a model

SYNOPSIS ^

  package App::Model::Fooble;

  use Jifty::DBI::Schema;
  use App::Record schema {
      column scribble => type is 'text';
      column wobble => type is 'int';
  };

  use Jifty::Plugin::Comment::Mixin::Model::Commented;

DESCRIPTION ^

Add this mixin to a model if you'd like to attach comments to it. Comments can be used to allow users of your system to comment upon and discuss the record to which they are attached.

METHODS ^

import

This method performs some rather devious magic to make everything work easily. It automatically generates an additional model for your application. This model will look something like this:

  use strict;
  use warnings;
  
  package App::Model::FoobleComment;
  use Jifty::DBI::Schema;
  
  use Jifty::Record schema {
      column commented_upon =>
          references App::Model::Fooble,
          label is 'Commented upon',
          is mandatory,
          is immutable,
          ;
  
      column the_comment =>
          references App::Model::Comment,
          label is 'Comment',
          is mandatory,
          is immutable,
          is distinct,
          ;
  };

  App::Model::FoobleComment->add_trigger( before_access => sub {
      my $self = shift;
      my ($right, %args) = @_;

      if ($right eq 'create') {
          return 'allow' if $self->current_user->id;
      }

      if ($right eq 'read') {
          return 'allow';
      }

      return $self->App::Model::FoobleComment::current_user_can(@_);
  });

You will need to define an before_access trigger for this class if you want it to be useful.

for_commenting

Returns a value to be used with the comment views. It's basically just a string identifying the class name and ID of the record.

comments

Returns a collection of Jifty::Plugin::Comment::Model::Comment objects that have been attached to the current record. (Actually, it returns the a collection of the local application class, e.g. App::Model::CommentCollection.)

comment_record_class

This is the name of the linking class that was created during "import".
